Hitachi Europe, working with Moixa and PassivSystems and part-funded by the European Regional Development Fund, has created a new energy platform for the Isles of Scilly.
Harnessing the power of the Internet of Things, it controls residential prosumer assets (heat pumps, hot water cylinders, batteries and an EV charger) to balance local energy generation and consumption and ensure curtailment of local generators is avoided at times of network stress.
The Universal Smart Energy Framework (USEF) was implemented as a day-ahead and intra-day trading mechanism between Hitachi’s Resource Management Server (acting as DSO) and the project partners acting as Aggregators for demand side assets.
When combined with the Aggregators’ machine learning capabilities, the solution is able to provide the best mix of demand side response, while at the same time ensuring consumer needs, such as comfort levels, are not compromised. In the day-ahead scenario, the platform predicts network stress and orders Flexibility for the next day to offset it against the prediction.
For the intra-day scenario, the platform receives curtailment events (as they happen) directly from the grid operator, evaluates the financial viability of offsetting curtailment with DSR and executes an immediate flexibility trading cycle, if appropriate.
